摘要:
This invention provides a vaccine which contains, per dose, an effective immunizing amount of a modified feline enteric coronavirus and a suitable carrier. The vaccine of this invention may also contain an adjuvant, an effective immunizing amount of a second modified virus and a an effective immunizing amount of a modified bacteria. Additionally provided by this invention is a method of immunizing a dog against disease caused by canine coronavirus involving administering to the dog a dose of the vaccine of this invention. The method of this invention may also involve administering one or more additional doses of vaccine to the dog, immunizing the dog against disease caused by a second virus and immunizing the dog against disease caused by a bacteria.

摘要:
L'invention concerne des compositions polymériques comprenant au moins une polyoléfine, au moins un amidon thermoplastique et au moins un composé ionique, ce dernier étant présent sous une teneur telle que la concentration en anions et en cations dans la composition soit de 0,002 à 5 moles/kg. Elle concerne également le maître-mélange utilisé pour la fabrication de ces compositions et contenant l'amidon thermoplastique et le composé ionique. Les compositions conviennent en particulier pour la production de films mono- ou multicouches utilisables notamment dans l'industrie de la papeterie.

摘要:
Disclosed is a method for causing the dissociation of microbial mycelium and extracellular lipase bound thereto and increasing the measurable activity of the lipase. The method involves treating an aqueous suspension of the mycelium with the anhydride of a discarboxylic acid which results in dissociation of the mycelium and lipase thereby facilitating recovery of the lipase.
